WASHING-MACHINE.

Specicaton of Letters Patent No. 27,825, dated April 10, 1860.

To aZZ 'whom it may concern:

vBe it known that we, J. M. PATTERSON and J. F. MORELL, both ofVoodbury, in the county of Gloucester and State of New J ersey, haveinvented a new and useful Improvement in )Vashing-Machines; and we dohereby declare that the following is a full, clear, and exactdescription of the construction and operation of the same, referencebeing' had to the annexed drawings, making a part of this specification,in which- Figure 1, represents a side view; and Fig. 2, a top view, ofthe said improved machine.

The nature of our invent-ion consists in the construction, andarrangement together, of a hollow, air-tight, corrugated, metalliccylinder, and a metallic tub or case, whose bottom itself is acorrugated concave-as hereinafter described-whereby we gain greatersubstantialness in the general construction of the cylinder and case ofthe machine, and at the same time diminish the comparative weight of themachine, and the cost of construction; and also, in the combinedarrangement, hereinafter described, Y of levers, pulleys and cords, foroperating the cylinder with greater facility and ease.

In the drawings, A, represents the cyliniler; and B, the concavesupported upon egs.

Like letters indicate the same parts when on both figures.

The cylinder (A) is made of sheet metal, and consists of a corrugatedperiphery c, attached to two end-disks eZ, CZ, through the centers ofwhich the axis e, projects. The corrugations 1 1, (shown by dot-tedlines in Fig. 1) are made in depth about one-seventh of the diameter ofthe cylinder (A), parallel with its axis (e), and of rounded form-asshown in the drawings. The concave (B) is also made of sheet metal, andis supported upon four legs f-f, as seen in the drawing, thecorrugations 2 2, being of about the same depth and form as those of thecylinder (A), and also parallel therewith, being attached to the endplates g, g, so as to make a water tight trough, whose bottom shall beconcentric with, and, about the depth of, the corrugations, distantfrom, the cylinder (A) when the latter is suspended upon the lowerbearings 71 h, over the concave. The bearings (t-t) consist of iron pinsmade adjustable in height by means of the receiving sheaths i, i, md z,i', for the purpose of allowing an increased space between thecorrugations of the cylinder (A) and those of the concave (B), in casean unusual quantity of clothes is required to be washed at once.

Through the space left on each side of the cylinder (B), the clothes areto be introduced into the machine. These spaces are fitted with lids, orcovers, 7c, k, which are hinged to the sides of the concave (B), as seenin the drawings.

Fast on the ends of the axis (e) are two levers Z, Z, which arerespectively connected to the hand levers m, m, on each end of theconcave case (B), by means of the cords n, n, which pass over pulleys j,j. The opposite ends of the levers (Z, Z,) being connected, by means ofthe springs 0, 0, to the front legs at p, p. Attached to the levers (m,m), by means of a cord g at each end of the machine, is a verticallysliding treadle r, which works in a slot or guide s, which is formedbehind each front leg (f, f,), as seen in Fig. l, which treadle givesthe operator a choice to operate either by hand or foot, or with both,as may be desired. Grooved pulleys may, if preferred, be substituted forthe levers Z, Z, as equivalents, or for the same purpose.

Operation: The clothes to be washed are placed in the concave (B)through either of the openings which are fitted with the hinged coversZe, k, with the hot soap-water, and the lids or covers shut down; when,by working the hand-levers (m, m) or treadle (1"), up and down, asemi-rotary, oscillating motion will be given to the cylinder (A), andthe clothes thereby rolled backward and forward, and also squeezed,between the cylinder (A) and the concave (B), in such a manner as, withthe consequent agitation and surging of the water, to soften and forceout the dirt, &c., from the clothes, in the most easy and expeditiousmanner, and without injuring the fabrics, or tearing off the buttons, asis the case in machines fitted with shallow corrugations, or grooves andridges of wood, adapted together to produce a sliding movement of thesame over the clothes.

The cylinder (A) simply rests upon its axis, by gravitation, and istherefore free to rise as the rolling of the clothes beneath it maysometimes require.

The whole machine is made either of sheet zinc, or galvanized sheetiron, excepting the springs o, o, which are made of vulcanized gumcloth, rolled up into a cylinder, its iron hooks t, t, being secured bytheir globular inner ends u, u, within the ends of the cylinder, bymeans of a wire wound around the ends of the cylinder, as seen in thedrawings.

The machine is, altogether, lighter, and cheaper of construction than ifmade of wood; is easily operated, either by hand or foot, and is notliable to derangement.

Having thus fully described our improved washing machine, and pointedout its utility, what we claim as new therein of our invention, anddesire to secure by Letters Patent, is-

l. The metallic, hollow, air tight, corrucylinder (A), and the metallic,concave and corrugated bottomed case or tub (B), the same beingconstructed and arranged to J. M. PATTERSON. JAMES F. MORELL.
